煤层瓦斯压力记录仪是瓦斯涌出和突出的动力也是标定参数准确测定煤层瓦斯压力对合理有效制定矿井防治瓦斯的措施预测预报煤与瓦斯突出的危险性具重要意义目前常用的煤层瓦斯压力测定技术大都在封孔段岩层坚硬致密的条件下有效但是由于受到封孔材料的限制对松软砂岩或钻孔周围存在微裂隙的情况下封孔效果不理想易于漏气使测出的瓦斯压力值低于煤层真实的瓦斯压力这样会导致错误判断从而造成事故隐患.设备原理主动式测压封孔方法是中科院周世宁院士最先提出的一种用于测定煤层瓦斯压力的封孔方法.该方法的封孔原理是在封孔两端用膨胀胶囊封孔中间注入压力略高于煤层瓦斯压力的密封粘液粘液在压力作用下不仅可以渗入钻孔与胶囊间的裂隙压力略高于煤层瓦斯压力的密封粘液粘液在压力作用下不仅可以渗入钻孔壁与胶囊间的裂隙而且还可以渗入钻孔卸压圈的裂缝和钻孔周围的天然裂隙中杜绝瓦斯的泄漏.这样形成了胶囊封粘液粘液封瓦斯的主动式封孔方法从而使测出的瓦斯压力值等于煤层真实的瓦斯压力
